The effect of air velocity on slugs in a confined channel
Flow Measurement and Instrumentation, 2021 The present work focuses on the study of slugs occurring in a two-phase flow of a confined rectangular channel: conditions of appearance and effect on the flow behavior. Three-dimensional numerical simulations have been carried out to examine the effect of superficial air velocity on flow behavior.

Computational fluid dynamic (CFD) modelling of transient flow in the intermittent gas lift
Petroleum Research, 2020 A computational fluid dynamics model (CFD) is developed for intermittent gas lift techniques. The simulation is conducted for a test section of 18 m vertical tube with 0.076 m in diameter using air as injection gas and oil as a formation fluid.
